Blend & adjust images
The aim here is to position, size and blend the two clips to achieve as clear an output as possible.
Select video A or video B
To adjust clips it is first necessary to choose which clip is to be adjusted. To do this, click the headings above either video A or video B:
It is not necessary to select either heading; if a selection is not made, video B will be adjusted. The currently selected video is indicated by a thin white border around the heading.
To adjust alignment
Realigning the video images can be useful if one performer is obscuring the actions of the other. To do this, point at the video image and move it by click & drag. The Align video must be "On" for this to work:
To resize (adjust zoom) images
If, because of camera position or zoom, the performer in video A is a different size from the performer in video B, the zoom can be adjusted for the selected video clip. To do this:
| 2. | Use the scroll wheel on your mouse to zoom in and out.
|
| Holding down the [ctrl] key, use [+] or [-] keys on the numeric keypad to zoom in or out.
|
The method for activating and using the numeric key pad varies from laptop to laptop, refer to your laptop's documentation.
Flip images
Using the flip buttons, you can still compare video images even if they contain left and right handed players or one has been filmed from the left side and the other from the right.
To use these buttons simply click them to switch them "on" and "off".
Adjusting transparency
Adjusting the dominance of one image over the other can often produce a more natural looking result. Experiment with adjusting the transparency by using the transparency slider.
If two backgrounds were extracted, the transparency slider is used to select which background you wish to use.
